Active and passive transports across the cell membrane differ in A. Passive transport is non-selective. B. Passive transport is along the concentration gradient while active transport is due to metabolic energy. C. Active transport is more rapid. D. Passive transport is confined to anions while active transport is confined to cations.

Answer
Passive transport moves molecules along their concentration gradient without energy, whereas active transport requires energy (usually ATP) to move molecules against the gradient.
